The canopy size of this patio umbrella is 11'X11', unique double-top canopy design for commercial and residential use.
This is exactly what I needed to get rid of the big ugly base on my umbrella. The holes for the umbrella base are tapped for M8 bolts. The outer holes work for 14 bolts. The base is powder coated dark grey with some metallic flakes.
This comes with 16 lag screws that are about 2” long. I didn’t use these as they wouldn’t sink far enough into the support joists.. Scott. San Diego, CA. Wed Aug 20 2025
